According to CINNO Research’s screen fingerprint market report data, 2020 is expected to become the first year of mass production of LCD screens supporting fingerprint recognition. Also, the source thinks this year’s shipments will exceed 6 million units and rapidly increase to 52.7 million units in 2021. By 2024, shipments of smartphones supporting under-screen (LCD) fingerprint recognition will grow to approximately 190 million units.
Under-screen fingerprint recognition is not exclusive to OLED technology
The LCD screen structure is more complicated than the OLED screen. The number of film layers is greater and the light transmittance is lower. It is also difficult to implement an optical fingerprint recognition similar to the OLED. In order to achieve better light transmittance and recognition, manufacturers need to optimize the optical film layers and glass of the LCD screen. They also have to change the structure of the screen film layer to improve the infrared transmittance.
At the same time, due to changes in the film layer and structure, the sensor originally located in a specific position under the screen needs to be modified. Therefore, LCD screens with under-screen fingerprints are more customized than ordinary LCD screens. The mass production process requires close cooperation between the terminal brand factory, the solution factory, the module factory, the film material factory and the panel factory, and the supply of terminal brands
Although the mass production and popularization of LCD screens supporting fingerprint recognition is challenging, as LCD screens still occupy a very large share of smartphones, major manufacturers still have sufficient motivation to adopt and launch products that use this technology. The LCD screen finally broke the original barrier and ushered in its second spring.
Who Is The First?
According to the CINNO Research, the under-screen fingerprint manufacturers that cooperated with the Redmi in terms of developing an LCD screen fingerprint are Fu Shi Technology. And the backlight film manufacturer is 3M Company.
On April 24, 2019, Fu Shi Technology released the world’s first mass-produced LCD fingerprint solution at the 2019 Spring Product Launch Conference held in Shenzhen. The relevant personnel of Fu Shi Technology successfully overcome this problem through a continuous reformation of the LCD backlight panel and adjustment of the fingerprint options. What’s even more commendable is that Fu Shi Technology has realized the rapid identification of fingerprint technology under the LCD screen through the advantages of its own algorithm. So it can compare this solution with the traditional capacitive fingerprint technology. Of course, their technology is constantly evolving and improving.
Compared with the OLED screens supporting fingerprint recognition solution, the advantages of the LCD screens supporting fingerprint technology are low screen cost and good sales. Even high-end smartphones will use this
